Just dyno'd my car. . .

[Almost Stock]

And I would like some info from longtime NSX'ers about my numbers and wether or not they are what would be expected.


First off i have a 91 5spd with 176k miles. My modifications are: Comptech airfilter, CT headers, Angus 100 cell cats, Pride v2 exhaust, and Prospeed stage 3 chip.

My max hp was 258rwhp and tq was 194. This was at about 1,000ft elevation. I don't have any pics of the run currently and the dyno run file is invalid to post here so I will get a pic and post it soon.

Let me know what you guys think.

Those are decent numbers. My '91 dyno'd at approx 266hp with 199 torque at near sea level with DC headers, R/M exhaust and ProSpeed stage 3 chip.

Here is a pic of the graph. . .

Those are good numbers, I think your car would like the RDX injectors (you're a bit lean under 5500 RPM). I really need to upgrade my exhaust...

I was thinking about the RDX injectors. I am also curious about that Bline(?) cold air intake, but I want to see some dyno numbers on that before I drop the money for it.

Numbers look pretty good with those mods. ~260hp with a few bolt on's sounds about right

I was under the impression that lean makes more power as long as u don't detonate.

Am I missing something here?

As far as I know that is correct. There is an old tongue in cheek saying your engine makes the most power just before you hole a piston or seize it(if you are running a two-stroke). On a two-stroke there is a very fine line between the most power and lean seizure. You need to be good at reading plugs. Little black specs on a pure white electrode and you are making really good power means you will probably be replacing rings or a piston soon.

Those numbers match some peoples dyno numbers at sea level. Good jorb.

Just ordered the RDX set up from Prospeed. Hopefully in a week or 2 I will have a dyno comparison to do.
